SWING-PIPE CABLE GUIDE AI\TD STUFFING BOX.

application filed October 1? 1921.

T 0 all whom-it may cmwern:

Be it known that 1, WILLIAM F. Eowanns, a citizen of the United States,residing at W'arren, in the county of Trumbull and State of Ohio, haveinvented-a new and useful Swing-Plipe Cable Guide and Stuffing Box, ofwhich the following is a specification.

This invention relates to storage tanks, and more particularly tanksespecially designed for storing oil or the like.

The primary object of the invention is to provide means to permit theswing pipe, forming a part of an oil storage tank, to be raised andlowered and at the same time maintain a gas-tight roof.

Another object of the invention is to support the usual pulleys overwhich the swing pipe cable moves, in a position to relieve the shell androof of the'strain usually directed thereto by the weight of the swingpipe.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings Figure 1 is a fragmental sectional viewthrough a tank constructed in 'accordance with the present invention.

Figure 2 is a plan view of the pulley support. A

Figure 3 is an elevational view partly broken away to disclose thestuffing box throu h which the swing pipe cable moves.

Re errin to the drawings in detail, the reference character 5 designatesan oilstorage tank embodying a metallic shell 6. a bottom section 7 anda roof section 8, the roof section being slightly inclined as clearlyshown by Figural of the drawings.

A swing pipeindicated at 9 has connection with the shell at a point inspaced relation with the bottom 7 of the tank, as by means of thesecuring rings 10 which embrace portions of the pipe, and contact withthe shell 6.

The pipe 9 includes an elbow 11, whereby the pipe may be swung withinthe tank Serial No. 508,267.

proper as clearly shown by Figure 1 of the drawings. The pulleys andbracket, which form an important feature of the invention, embody aplate 12 to which are secured the upstanding spaced cars 13 whichprovide bearings for the shaft 1% that supports the pulleys 15, overwhich the swing pipe cable 16 moves.

Secured to the plate 12 are the bracket members 17 which have bearingmembers accommodating the shafts 18 of the pulleys 19, which pulleysoperate in close proximity to each other, the cable 16 passingtherebetween. The plate 12 is provided with a suitable openingcommunicating with an opening formed in the stufiing box 20 which is beted to the plate 12 as by means of the bolts 21 and disposed at an anglewith respect to the'upper surface of the plate to feed the cabledirectly through the pulley 15.

The stufiing box 20 is formed with a hollow portion to accommodate thepacking material 22, the inner surface of the stuffing box beingthreaded to accommodate the threaded portion 23 of the movable section24 of the stuffing box, which movable section is also provided with anopening to accommodate the cable 16.

This cable 16 has one of its ends connected to the swing pipe 9 as at25, the opposite end thereof having connection with the Windlass 26which is operated by the crank handle 27, so that the cable 16 may bewound on the windlass to move the swing pipe 9 so that the free endthereof may assume positions within the tankat various levels.

From the foregoing it will be seen that as the cable 16 is wound on thedrum, and moves through the stu'ding box, an air-tight connectionbetween the cable and stuffing box is provided. If it is desired toprevent leakage of gas between the cable and stuffing box, should thestuffing material 22 become worn, it is only necessary to rotate themovable section 24; of the stufiing box to cause the stuffing material23 to again closely engage the cable 16.

7 s clearly shown by Figure 1 of the drawings, an angle iron indicatedat 28 has connecticn with the shell 6 and braces the overhanging portionof the roof 8. 12 is positioned on the roof at a point adjacent to theangle iron 28 and as shown, the pulley 15 is supported directly over theen- The plate gle iron 29 to relieve the shell 6 and roof 8, of thestrain directed thereto, when the swing pipe is being moved.

Having thus described the invention, what is claimed as new is 1. Incombination with an oil storage tank and the Swing pipe supportedtherein, a plate supported on the roof of the tank, pulleys supported bythe plate, a stufiing box forming a part of the plate, a cable adaptedto pass through the stufiing box and adapted to move over the pulleys,said cable having connection with the swing pipe, and a windlass formovingthe cable over the pulleys to ad'ust the swing pipe.

2. n combination with an oil storage tank and the swing pipe supportedtherein, a

plate supported on the roof of the tank, pulcable adapted to passthrough the stufiing box and over the pulleys, said cable havingconnection with the swing pipe, and means lfjor moving the cable throughthe stuffing In testimony that I claim the foregoing as my own, I havehereto aflixed my signature in the presence of two witnesses.
